Automatic Fault Localization for BIP

This paper presents a novel idea of automatic fault localization by exploiting counterexamples generated by a model checker. The key insight is that, if a candidate statement is faulty, it is possible to modify (i.e. correct) this statement so that the counterexample is eliminated. We have implemented the proposed fault localization algorithm for component-based systems modelled in the BIP (Behaviour, Interaction and Priority) language, and conducted the first experimental evaluation on a set of benchmarks with injected faults, showing that our approach is promising and capable of quickly and precisely localizing faults.
